Well, it's a bullet. Bullets can be used pretty much anywhere, though I'd suggest using this on the clitoris if you're a lady. Because it can be hard to hold due to the heavy vibrations of the bullet, it may be uncomfortable for play where you have to hold it in place manually, or where it's being moved across the body. It stays against the clitoris pretty well just by holding a small pillow or something else over it. It's not designed for internal use, so don't go more than maybe half an inch to an inch in when playing with an orifice. It has a seam around its middle and a hole where the cord goes in, so it's not really capable of being fully cleaned (this is also why you shouldn't insert it). I suggest only using this for yourself or in a monogamous relationship. It does heat up with extended use. It also numbs your hands if you hold it for a bit, so shorter sessions are preferable.

There is no smell whatsoever and no discernible taste. The plastic is hard and smooth. Its seams will prove uncomfortable if you forget yourself and insert it too far (as I did).

This is the absolute classic bullet. It is egg shaped and smooth, with good hard vibrations. The cord is decently long (2 1/2 ft, I believe), which I like. All in all, it's pretty much the traditional bullet. I do wish there wasn't the seam around the middle of the bullet, or even that it was totally water tight so I could insert it, but for such a cheap product it's amazing.

The vibrations are all over the egg, without a single point of intensity. The controls are a simple wheel, which can be turned on either side of the tear-shaped controller. I think dial controls are the best, although it means that if you intend to travel with it, you should take out the batteries so it doesn't accidentally switch on. The vibrations are deep and pretty strong even on the lowest setting. If you prefer weaker vibrations, that can be solved by using it over underwear or even sheets. If you hold it for a while, your hand WILL go numb. Holding it with gloves or through sheets might be a good idea. It also heats up with extended use, which can be nice, or it can be painful! It's a bit loud. It has more of a deeper, rumbly register that's not as distracting as the buzzy whine of most bullets. I can still hear it under two comforters.

Since it is plastic, pretty much any lubricant will work, even oils. I'd be cautious of the seam and the hole where the cord goes in, though. Use soap and water, but don't soak it (wipe on, wipe off) because it's not waterproof. You probably shouldn't store it with the batteries in since it might go off accidentally, although I leave them in and have never had a problem.
